With the foregoing configuration, a manufacturing process for the billiard ball according to the fourth exemplary embodiment of the present invention is as follows.

As shown in FIG. 11, three design bars 102, 104 and 106 are prepared.

The three design bars 102, 104 and 106 are circular bars, and include a first bar member 102 which is arranged vertically, a second bar member 104 which is connected in the left and right from a center of the first bar member 102 and a third design bar 106 which is connected in a forward and backward direction from a center of the first bar member 102. That is, the three design bars 102, 104 and 106 pass through the center of the main body 10 and are arranged in axes X, Y and Z respectively.

A design portion 110 is formed in both ends of the design bars 102, 104 and 106. The design portion 110 may be formed by printing a design in both ends of the design bar, or additional material having a design therein may be attached or may be engraved.

As shown in FIG. 12, the design bars 102, 104 and 106 are put in molds 120 and 122 to form the main body 10.

When the design bars 102, 104 and 106 are put in the molds 120 and 122, a positioning device (not shown) may be used to arrange both ends of the design bars 102, 104 and 106 in an edge of the molds 120 and 122, i.e., face the molds 120 and 122 at around an internal surface of the molds 120 and 122.

Then, resin is injected to the inside of the molds 120 and 122. The resin surrounds the design bars 102, 104 and 106 and is cured to form the main body 10. The resin may have the same color as that of the billiard ball which is to be manufactured.
